If you’re preparing for power outages, you’ve probably asked the big question:
Should I buy a solar generator or a gas generator?
Both can provide backup power — but they solve different problems.
This guide compares solar generators vs gas generators in plain English, so you can choose the right option for your home, apartment, or emergency plan.
Quick Comparison (Solar vs Gas)
| Feature | Solar Generator | Gas Generator |
|---|---|---|
| Safety | Safe Indoors, No Fumes Or Carbon Monoxide | Must Run Outdoors (Carbon Monoxide Risk |
| Noise Level | Very Quite - Fan Noise Only | Loud Engine Noise |
| Maintenance | Minimal (Keep Charged) | Oil Changes, Fuel Stabilizer, Periodic Servicing |
| Runtime | Limited By Battery Size (Extend With Solar Panels) | Runs As Long As Fuel Is Available |
| Best Use Case | Indoor Essentials (Fridge, Lights, WiFi, Medical Devices | High-Power Tools. Long Heavy-Load Runtime |
1) Safety (Biggest Difference)
Solar generator
✅ Safe indoors
✅ No carbon monoxide
✅ No fumes
✅ No fuel storage
Gas generator
❌ Carbon monoxide risk
❌ Must run outdoors
❌ Requires gasoline storage
❌ Higher fire risk if mishandled
If you want indoor-safe power, solar generators win easily.
2) Noise
Solar generator
✅ Silent (only a fan)
✅ Apartment and RV friendly
Gas generator
❌ Loud
❌ Can upset neighbors
❌ Not ideal for overnight use
If quiet matters, solar generators are far more comfortable.
3) Ease of Use
Solar generator
✅ Plug-and-play
✅ Minimal maintenance
✅ Charge from wall or solar
Gas generator
❌ Oil changes and maintenance
❌ Fuel management
❌ Startup procedures and storage concerns
For most households, solar is simpler.
4) Runtime & Power
Here’s where gas generators can shine.
Gas generator
✅ Can run as long as you have fuel
✅ Often higher continuous output
Solar generator
✅ Limited by battery size
✅ Can extend runtime with solar panels
✅ Great for essentials (fridge, lights, devices)
If you need high-power tools or multi-day runtime with heavy loads, gas can be useful.
If you need safe indoor essential power, solar is usually the better fit.
5) Cost Over Time
Solar generator
-
Higher upfront cost
-
Very low ongoing cost
-
No fuel required
Gas generator
-
Often cheaper upfront
-
Ongoing fuel costs add up
-
Maintenance costs over time
For frequent outages, solar can be cheaper long-term.
Which One Should You Choose?
Choose a solar generator if you:
-
want indoor-safe backup power
-
need quiet operation
-
live in an apartment or RV
-
want low maintenance
-
want to run essentials (fridge, lights, Wi-Fi)

Choose a gas generator if you:
-
need high continuous power (tools, larger loads)
-
expect long outages and have fuel storage
-
can safely run it outdoors away from windows
Best Setup for Most People (Hybrid Approach)
Many families choose:
-
Solar generator for daily essentials (quiet, safe, overnight)
-
Gas generator only if needed (short high-load tasks outdoors)
This gives you flexibility without relying on gasoline for everything.
FAQs
Can a solar generator run a refrigerator?
Yes — most 1000Wh+ models can run a fridge for 8–12+ hours depending on usage.
For detailed runtime examples, see our guide on the best solar generators for refrigerators.
Are gas generators dangerous?
They can be if used improperly. Carbon monoxide is the biggest risk.
Are solar generators worth it?
For safe indoor essentials and low-maintenance backup power, yes.
Final Recommendation
If your goal is reliable backup power for essentials during outages — especially indoors — a solar generator is the safest and simplest option for most homes.
A mid-range unit like the Jackery Explorer 1000 series provides enough power for refrigerators, lights, and Wi-Fi without the noise and maintenance of a gas generator. (Specifications may vary slightly depending on the current manufacturer version.)
If you need high output for heavy loads and have safe outdoor space and fuel storage, a gas generator can be helpful as a secondary tool.
